What is a plugin for Yandex.Browser

Despite the fact that Yandex.Browser itself boasts high performance and stability, many users have problems with the operation of various plugins. Moreover, both extensions from official sources and third-party ones, including self-written ones, do not work correctly. Let's look at the causes of such problems and get acquainted with ways to eliminate them.

What is a plugin for Yandex.Browser?

A browser plugin is third-party code designed to extend the functionality of the browser. In other words, this is an add-on created to make browsing the Internet more comfortable. Plugins are an important part of any browser, since surfing the Internet without such add-ons becomes incomplete.

Main problems associated with using plugins

As a rule, errors appearing when installing plugins are the result of either compatibility issues or an oversight on the part of the browser or plugin developers.

Sometimes, when trying to launch a video, game or music, users encounter the following error: “Failed to load plugin.”

The image may change over time, but the meaning will remain the same

Common problems include the following:

  • Flash Player error. Occurs when the plugin or browser version is outdated;
  • loading a (cached) version of the page saved in the PC memory. If the browser saved a page in the PC memory without using the plugin, then there is a chance that it will load it even if the plugin is not enabled;
  • obsolescence of the current browser version. The program may be too old to work fully on new systems;
  • programs that disrupt the system. These include viruses, ad integrators, etc.;
  • The problem is at the operating system level. The OS version is too old, the update was installed incorrectly, etc.;
  • conflict (incompatibility) of two plugins.

Let's consider several options for solving problems.

Plugin conflict

If next to the plugin name there is the text “2 files” enclosed in brackets, then the cause of the problem is most likely a conflict that interferes with the normal functioning of two elements at once. To resolve it, follow the instructions:


Most often, this problem occurs when using Flash Player, so the first thing you should try is to disable it. But this method is applicable not only to this extension.

Page caching error

This error occurs rarely, but you should not avoid it. To fix it, clear your cache and cookies so that the browser creates new ones:

Virus or adware

By downloading files from unverified sources, the user always runs the risk of receiving something unwanted or even dangerous to his privacy along with the desired information. It could be a banal toolbar with a bunch of technical problems, a virus that steals passwords, a cryptocurrency miner, or an advertising integrator. It is the second and last that can disrupt the operation of the browser, including plugins.

  1. Check the list of browser extensions by typing “browser://tune” (without quotes) into the address bar. If you find something suspicious, try turning it off and check if the problem remains. As a rule, integrators of additional advertising are disguised as services that report weather information, but they are made in haste and can cause problems with browser performance and the operation of some plugins.

  2. Update your browser, operating system and antivirus (if available). Windows Defender may not be enough.
  3. Enable the aforementioned Windows Defender if it is disabled. To enable this element of the system, you need to enter the query “Windows Defender” in the Start menu. In the window that opens, find the “Options” item and move the slider under the “Real-time protection” item to the active position.

  4. Perform a full scan of your PC with an antivirus. You can also use the Dr.Web CureIt utility, as it is distributed free of charge and allows you to quickly scan your computer and then eliminate threats.

From personal experience I can say that advertising integrators are not always identified as a virus. Even a schoolchild can write something like this, and you can come up with enough variations of such programs so that they do not have time to get into the databases of anti-virus applications in time. In my opinion, the best protection here is simple caution when downloading files from the network.

The plugin is not supported by the browser

There may be several reasons for this problem:

  • outdated version of the plugin or browser. It can be solved by updating or reinstalling one of the components, and for reliability - all of them;
  • partial incompatibility with the current version of the operating system. As a rule, it occurs when installing an old version of the browser on a new OS or a relatively new one on an old one. There is no clear version compatibility table, so this problem is solved by updating the system and browser to the latest versions.

The algorithm for solving the problem is similar to that used for the Google Chrome browser.

General recommendations for fixing problems in the operation of plugins for Yandex.Browser

Let's look at a number of problems that do not occur so often.

Plugin disabled

The plugin could probably just be disabled by default. To solve this problem you need to enable the plugin.

The plugin settings window allows you to turn them on and off

Left-click on “Enable”. It is also recommended to click on the “Always run” checkbox.

Browser auto-update does not work

Of course, Yandex Browser provides automatic updates. However, errors may appear that interfere with this process. Try updating the program manually.

To do this, type browser://help in the address bar and press Enter. If there is an “Update” button on the page, then your version is indeed outdated. Once the installation is complete, the Restart button will appear. Click on it for the changes to take effect.

What to do if none of the methods helped

If the problem occurred recently, and the browser once worked correctly, then you can perform a system restore. It will “roll back” your OS to a checkpoint.


If even this does not help, then it's time to reinstall Windows.

To prevent problems with your browser, follow these rules:

  • do not download files from unverified sources;
  • do not delete system files;
  • update your browser, antivirus and operating system on time;
  • Periodically scan your PC memory for malware.

The author recommends that you note that there are two ways to restore the system: without deleting files and with deleting files. Inattention when choosing one of the options can lead to the loss of files that appeared on the PC after creating a recovery point.

Despite the abundance of all kinds of problems with Yandex.Browser, it is quite simple to solve them, and even easier to avoid them by taking timely care of PC security.
